# Edelbrock Timing Chain And Gear Set Buick 455 Edelbrock part #7840 Performer-Link timing chain is for use with Edelbrock or stock cams. They have a solid-bushing chain for a true bearing surface that rolls with the sprockets, eliminating chain stretch. Cam sprockets are made from 35,000 psi tensile strength cast iron. Crank sprockets are made from billet SAE-1144 steel and induction heat treated. Four Performer-Link sets are stock replacement parts and 50-state legal (see listings in bold type). All other sets have three keyway setting points to ensure accurate timing selection for early or late-model vehicles. Performer-Link timing sets are not for use above 6500 rpm- ? Performer roller chain sets are engineered to operate up to 6500 rpm.- ? Never hammer directly on chain or sprockets. You can crack the hardened links and pins and cause early failures. - ? Use a sleeve for installations that require hammering, a brass drift punch may be used if you carefully alternate blows on either side of the sprocket to avoid cocking. - ? Never stretch the chain with a screwdriver. - ? Check for clearance between the timing chain and block and between the chain and front cover before reassembly. - ? Be sure that both cam and crank sprockets are exactly in line with each other. Misalignment can cause chain to break - True Bearing Surface Rolls with the Sprockets This Part Fits: Year Make Model Submodel 1971-1973 Buick Centurion Base 1973-1974 Buick Century Base 1973-1974 Buick Century Luxus 1968-1974,1976 Buick Electra 225 1968-1974 Buick Electra 225 Custom 1974 Buick Electra 225 Limited 1967,1973 Buick Electra Base 1967,1975 Buick Electra Custom 1975-1976 Buick Electra Limited 1970-1976 Buick Estate Wagon Base 1967 Buick Gran Sport Base 1968-1969 Buick GS 400 Base 1970-1972 Buick GS 455 Base 1970 Buick GS 455 GSX 1970-1975 Buick LeSabre Base 1970-1973,1975-1976 Buick LeSabre Custom 1974 Buick LeSabre Luxus 1973-1974 Buick Regal Base 1967-1976 Buick Riviera Base 1971 Buick Riviera Gran Sport 1975 Buick Riviera GS 1976 Buick Riviera Sport 1976 Buick Riviera SR 1967-1968,1970 Buick Skylark Base 1968,1970 Buick Skylark Custom 1968,1970 Buick Sportwagon Base 1968 Buick Sportwagon Custom 1967-1969 Buick Wildcat Base 1967-1970 Buick Wildcat Custom ## Details - **Price:** 195.15 CAD - **Vendor:** Edelbrock - **Type:** Timing Chains ## Variants | Variant | Price | Available | |---------|-------|-----------| | Default Title | 195.15 CAD | In stock | ## Images - Photo - Primary - Photo - Primary - User 1 - User 4 - Photo - out of package - Photo - Unmounted - User 3 --- > Source: [Standard Auto Part](https://www.standardautopart.com/products/edelbrock-timing-chain-and-gear-set-buick-455) > Updated: 2026-06-27
